Available in frame sizes from 12 to 40 channels, the GB4 is designed for installations such as churches and performance venues, or for small touring sound systems. The dual-mode topology implemented successfully on the MH3 and MH4 desks allows the GB4 to be used on FOH or monitor duties, with fader control of group or aux outputs.
Although largely conventional in layout, the GB4 has some unique mechanical features. The rugged steel chassis has a sloping rear connector panel, making it easier to configure from the front of the desk, while the integral power supply has a link option for an external back-up PSU. Four mute groups allow several channels to be muted simultaneously, while another unique facility is the limiter on a set of dedicated record outputs that makes it easier to create a stereo recording of the mix.
The console also features an output matrix with seven feeds to four outputs, being fed from the group busses and main L, R and C (mono) outputs. The GB4 offers a comprehensive set of functions and facilities in a small and cost-effective footprint, say the manufacturer.
